Trigonometric Substitution

This calculus video tutorial provides a basic introduction into trigonometric substitution. It explains when to substitute x with sin, cos, or sec. It also explains how to perform a change of variables using u-substitution integration techniques and how to use right triangle trigonometry with sohcahtoa to convert back from angles in the form of theta to an x variable. There's plenty of examples and practice problems in this lesson.

Trig sub is one of the hardest integration techniques to learn and you explain it in such an easy to follow way.

[@citizencj3389]

It's actually the hardest to learn because you need full knowledge of trig identities, sohcahtoa, and even inverse trig functions to solve some of these.

Honestly, I hope you succeed in whatever things you do. I wish you many more blessings in your life. You mean so much to your students. I hope you freaking go viral and gain many supporters. I don't understand how celebrities could be going viral for doing the mundane things, but our educators can't even get the recognition they deserve, as they are the ones actually changing lives. You guys deserve an award for all your hard work. I guarantee you that your hard work and dedication don't go unnoticed. We see you grinding and hustling, so thank you from the bottom of my heart. You are literally an underrated genius. Thank you so much, even words can't express how grateful we are for you. You always pull through at the right time for us all. Don't ever stop posting! I don't think I will stop watching your videos even if I finish school, just for the sake of learning and sharpening my skills. Knowledge is power and you inspire so many of us to keep learning no matter what.

I wish this channel had been around when I was in undergrad. I remember watching my professor explain this and wondering why this class was a requirement for Econ at UCLA.

When it comes to finding the missing side of the right triangle, it's worth noting that it always turns out to be the square root from the original integral that made us need to do a trig sub in the first place
